I painted this room and removed old light fixture. I would like to install ceilling fan this time.
I only have 3 wires inside and there are no blue, black or green inside as mentioned in some yotube tutorials that I've seen.
Can you tell me if this ceilling can support fan which will be definetely heavier? Do I need more wires? Is it ok that there is only 1 switch on the wall?





I also took photo of how wiring was connected under light fixture. As you see red wire goes nowhere. Is red wire made for fan? Should I believe that this rectangular structure was made to support fan?

 

You have a conduit system there based on the wire colors.
Red = always live or un-used, yellow = switched, white = neutral.
Since there is one switch in a single box then red is either always live or not connected.

Since you have the wiring that would be needed for a fan at that location it appears that a fan being installed there was anticipated. It's only a guess. A close up picture of the inside of the box would be helpful. It looks like a 4" square (1900) box with mud ring was used.

Almost any box properly installed will take weight but it's the movement of the fan that causes issues.

The fan to house wiring connections are based on the fan purchased.

 

There is metal box in the hole.
I installed brand new ceilling fan.
At first fan and lamp didn't work. I found out that black wires coming from receiver are not the same.
I rewired it again and left red wire alone.
Lamp started to work, fan too...
but the motor is humming.
I listened to all parts separately. Sound comes from motor and it is constant. It stops for 1-2seconds only when I change fan spped or direction.
Humming sound stops when I hit "power off" instantly. So nothing is loose, nothing hits or scratches anything.
Humming is different... (probably) louder when I change speed of fan.
I googled a little and rechecked everything.
Wires are connected good.
All screws are tight. Blades installed correctly with washers.
No dust, it is new.
I called customer service and they told me that ceilling fans usually need to "break in" for 24hrs.
12hrs passed and I still hear humming in painted room.
Any ideas?

There is no "break in" for a fan!

 

I just came from the store with second box. I installed the motor, rod and connected wires. The lamp and blades are still in the box.
Same humming sound.

24hrs from the manual

Second fan rewired

Left side:
3 green wires (mtn bracket + receiver + motor)
2 white wires (outlet box + receiver)
1 black + red wire (same issue with yellow)

Right side connects motor to receiver:
Orange + Orange
Yellow + Yellow
White + White
Black + Black
Blue +Blue

All together: With this configuration I left red wire coming from outlet box hooked up and yellow alone. There is also black antenna wire in front.

I recorded video of how the second fan works.
I start with low speed. Then around 42sec I hit medium speed and around 1min I hit high speed. I touched all parts of housing and the sound changes a little but not for better.

I have never seen a fan where you had to wire the entire controller/receiver like that.
That module is typically down in the motor area.
A basic remote is two power wires and three to the fan.

I see Patriot lighting on the paperwork. Is that the brand ?
Is the canopy humming ?
Hard to really test a fan without the blades on it .

 

1. Have you seen both videos? First one was with blades.
2. Should I leave yellow or red wire hooked up?
3. Yes, receiver looks like a rectungular remote withwires on sides. Manual told me to push it into mounting bracket and ceilling.
4. Yes, it is Patriot Lighting.
5. The manual tells me to connecr 4 green wires. I only have 3. The missing one should come from outlet box. There is only white, yellow and red coming from the box.
Is this a problem?
6. The humming sound comes definetely from motor but I did few tests. When I removed downrod from mtn bracket and hold the whole thing( rod, wires, canopy, motor) in hand the humming sound was twice less.
It looks like 50% of sound comes from motor, 20% from moving parts (rod, canopy, cover) and 30% cones from this metal outlet box in the celling.
This outlet box is probably the biggest problem. It acts as cave and the huming sound spreads and increase through it. Is it removeable without destroying ceilling?
I think I should add some spacers, washers, plastic/insulation pads everywhere, under every screw and every moving part.
Maybe this is why this is the only room without ceilling fan.
